Answer:
Step-by-step explanation:
We know that normal distribution as special characteristics such as symmetry, unimodal, no skewness, mean =median=mode, etc
A standardized variable for normal variable X is
will be normal with mean =0 and sigma =1
The probability will be divided equally on either side of the mean =0 i.e. y axis
Hence the answers would be
A standardized variable always has a mean of __0_____ and a standard deviation of ___1____. b. The z-score corresponding to an observed value of a variable tells you ____the std normal score.___. c. A positive z-score indicates that the observation is __to the right ____ the mean, whereas a negative z-score indicates that the observation is __to the left_____ the mean
Given:
1/2 pound of flour
split the flour into 3 bags of equal weight.
1/2 ÷ 3
In dividing fractions, you must remember to get the reciprocal of the 2nd fraction and multiply it to the 1st fraction.
3 is the 2nd fraction. Its reciprocal is 1/3
1/2 * 1/3 = 1/6 pound of flour.
The False statement is:
C. Each bag has 1/3 pound of flour.
Answer:
